Police are appealing for the public’s help to piece together Conley Thompson’s last movements as part of the investigation into the seven-year-old’s death.

The tragic youngster, from Underwood Avenue, Worsbrough, was reported missing after he failed to return home from Locke Park, Barnsley, where he had been playing with friends on Sunday night.

His body was found on by construction workers on a building site on Bank End Road, close to his home the next morning. He had fallen into a vertical pipe.

Conley left his home address on Underwood Avenue in Worsbrough Dale just after 6pm, after telling his mother he was going out to play without saying specifically where he was going.

He was reported missing to police at 10.10pm and searches took place throughout the night.

Senior Investigating Officer Detective Chief Inspector Dave Stopford said: “To establish the circumstances leading up to this tragic incident, we need to confirm exactly where Conley went after leaving his home shortly after 6pm.

“Initial suggestions at the time indicated Conley may have gone to Locke Park, however, and as the investigation continues, we now believe he may not have met up with friends and potentially ventured elsewhere before he went to the construction site, where he was sadly discovered yesterday morning.”

Conley was wearing very distinctive clothing when he left his home on Sunday evening. His shoes were red and black and he was wearing brown trousers with a light blue checked shirt. He had a grey hoodie and a black Helly Hansen hooded jacket.

DCI Stopford added: “We need to piece together Conley’s last movements to be able to understand what may have led him to the construction site and to include as much information as possible in the file we are preparing for the Coroner.

“I would please urge anyone in the areas of Worsbrough Dale, Worsbrough Common, Kendray and the surrounding locations, to please think back to Sunday evening and if you may have seen Conley, either alone or within a group, and to please contact the police.”

If you have any information, please call police on 101, quoting incident number 1148 of 26 July, 2015.
